Map pathVariables = (Map) request.getAttribute(
HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE);
String classId = (String)pathVariables.get("classId");// 获取某个班级下面的学生列表
@RequestMapping("/classes/{classId}/students")
public String list(@PathVariable String classId){
return "学生列表";
}package com.example.demo;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.HandlerMapping;
import org.springframework.web.servlet.ModelAndView;
import java.util.Map;
public class SpringMVCInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {
Map pathVariables = (Map) request.getAttribute(HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE);
String chatbotId = (String)pathVariables.get("classId");
System.out.println("classId: " + classId);
if ("1234".equals(classId))
return true;
return false;
}
@Override
public void postHandle(HttpServletRequest request,
HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
// TODO Auto-generated method stub
}
@Override
public void afterCompletion(HttpServletRequest request,
HttpServletResponse response, Object handler, Exception ex)
throws Exception {
// TODO Auto-generated method stub
}
}package com.example.demo;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
@Configuration
public class MvcInterceptorConfig extends WebMvcConfigurationSupport{
@Override
protected void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new SpringMVCInterceptor()).addPathPatterns("/chatbot/**");
super.addInterceptors(registry);
}
}请求路径url 上有个变量值，可以通过@PathVariable来获取
id为变量值：
@RequestMapping(value = "/page/{id}", method = RequestMethod.GET)Tool tool = new Tool();
tool.setUrls(new String[]{"finance/account/loanDownExcel/cur","finance/account/loanDownExcel/all"});@RequestMapping("accountlog/loanDownExcel/{type}")
public void exportAccountLogExcel(@PathVariable("type") String type)throws Exception {}或者是
public void exportAccountLogExcel(@PathVariable String type)throws Exception {}以上是“怎么在拦截器中获取url路径里面@PathVariable的参数值”这篇文章的所有内容，感谢各位的阅读！相信大家都有了一定的了解，希望分享的内容对大家有所帮助，如果还想学习更多知识，欢迎关注亿速云行业资讯频道！
